Hi, I have made a little Duophonic patch within FLStudio 11 using PizMidi plugins (Midi Note to CC, Midi Note Map, and MidiPolyphony). Not sure how useful this is for people on this forum, but figured I’d upload it. It works pretty well with a couple limitations. I had to mute Oscillator 1. I know that there is an ipad app out there that uses all three, but I have no idea how he did it, so I’m sticking to Oscillators 2 and 3. Secondly, you get hanging notes if you play lines monophonically, so I set a switch between Poly and Mono mode to connect to the mod wheel. You can change this to whatever controller.
I can certainly try to explain this patch to anyone that wants to try and improve it or has questions. It might not be the best way of doing it. But it does span a 5 octave keyboard pretty well. Hopefully it would work on someone else’s setup too. I put some notes within the FLP file as well for initial setup.
PizMidi plugins are here:

The site sometimes loads and sometimes doesn’t, but it’s all freeware.
Here’s the FLP file:

I think it could easily be ported to an Ableton rack or something, but for someone that knows how to build patches in Max MSP or make VSTs, there’s probably a much more self contained way way of doing it.
